Application filed March 5,

To all whom z't may concern:

Be it known that i, CHARLES F. SCHILL- ING, a subject of the lung of Great Britain,

and resident of the town of-Lacombe, in the Province of rilberta,-Dominion of Canada, have invented certain new and useful Improvements in Vertical Grates, of which the following is a specification.

This invention relates to improvements in vertical grates, and the objects of the invention are to provide simple and effective means for adjusting the position of a vertical grate in order to regulate the air feed, at the same time to provide means by which it may be more readily attached in position in a stove or furnace.

Other objects of the invention are generally to improve and simplify the construction of the grate to better adapt the various parts to perform the functions required of them.

It consists essentially of the improved. construction hereinafter described in detail in the accompanying specification and illustrated in the drawings.

In the drawings:

Figure 1 is a sectional elevation of an embodiment of the invention in a stove.

Figure 2 is a sectional elevation of the grate portion alone.

Figure 3 is a sectional plan.

Figure 4 is a perspective view of the cam mechanism for raising and lowering the grate.

Figure 5 is a plan view of the grate.

Figure 6 is a sectional elevation with the grate in raised position.

In the drawings like characters of reference indicate corresponding parts in all the figures.

Referring to the drawings:

A represents a suitable stove 01' furnace having a combustion chamber B and ash pit C. D indicates the grate including an outer horizontally extending annular portion 10 and a central or inner vertically movable portion 11. The outer portion is designed to be secured to the ring 12 attached to the casing 13 of the stove. The horizontal grate 1.0 may also be formed with a plurality of perforations 14, and a flange may conveniently enter a groove 15 in the edge of the grate 10, being held by lugs 15 which pass through recesses 15 when the grate is being placed in position.

The vertical grate 11 is cylindrical in form 1921. Serial No. 449,703.

and includes a top grate l9 and a plurality of parallel vertically extending grate'bars 2O conveniently formed integral with the top portion. Movement of the vertical grate upwardly and downwardly is caused to take place by means of a cam shaft 21 journalled in a ring 22, which depends from the grate 10, the cam shaft being provided with cams 24 and 25 which are adapted to engage pins 26 and 27 on opposite sides of a depending standard 28, formed with a vertical slot and secured to the grate 19.

In the embodiment illustrated, the standard 28 is formed with a flanged head 29 which is: inserted in the grate 19 during the casting of the same whereby when the casting is cool, the rod 28 will be rigidly supported in position.

It will be seen that, owing to the engagement of the cams with the pins, the grate will be raised and lowered. A plurality of pins are provided on the standard 28 on each side in order that the grate may be adjusted to different heights.

It will be seen that, when the vertical grate is raised above the surface of the horizontal grate, the air may pass readily through the vertical grate into the fuel in the combustion chamber.

As many changes could be made in the above construction, and many apparently widely difl'erent embodiments of my invention within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

1. A grate of the character described, comprising an outer horizontally extending annular portion formed with a central opening, a vertically movable grate mounted in the central opening having a depending standard, a cam shaft having spaced cams thereon on opposite sides of the standard and means on the standard engaging the cam in such a way that the standard is adapted to be raised successively by opposite cams when the shaft is turned.

2. A grate of the character described comprising an outer horizontally extending annular portion having a depending ring, and formed with a central opening, a vertically movable grate mounted in the central opening formed with a plurality of grate bars,

a standard connected to the vertically II 1OV- able grate having pins on opposite sides thereof, and a cam shaft journalled in the depending ring having cams adapted to' en gage the aforesaid pins-and thereby raise and lower the vertical grate.

3. A grate of the character described; coinprising an outer horizontally extending perforated annular portion having a depending ring and formed with a central opening, a vertically movable grate provided in the central opening formed with a plurality of grate bars, a standard forined With a verti cal slot,"a, head on the standard connected to the vertically movable grate, the standard 15 pins and thereby raise and loWer the verti- 20 cal grate.

In .witne ssvw hereof I have hereunto set my hand in the presence of two Witnesses.
